Assuming that the equation is 4.7x+3.8=13.2:
4.7x=9.4 - isolate x on one side
x=2 - divide 9.4/4.7 to solve for x
The answer is C.
Answer:
A) A line
Step-by-step explanation:
Notice that:
x-y=4
-y=4-x
y=-4+x
y=x-4
The equation y=mx+b produces a line, so A) a line would be correct
Answer:
None of the above, f(5) + g(-3) = 19.
Step-by-step explanation:
Given f(x)=2x+4 and g(x)=x2−4, determine the value of (5) + (−3). Assume that is supposed to be f(5) + g(-3).
f(5) + g(-3) = 2×5 + 4 + (-3)^2 - 4
= 10 + 4 - 4 + (-1)^2(3)^2
= 19
